I work in a primary school and have done since September as an apprentice. There’s a few y6 boys who keep mocking me and sniggering and making weird noises when near. At first I’m just ignoring but it’s been going on for ages and I know they’re saying not nice things about me and having a private joke about something. I know it sounds silly but it’s everyday when I come to work. (I’m not teaching staff). They’re even taking it further now and I think making personal comments about me. I don’t think they do it when alone, it’s when they’re together. How can I not let it bother me
